Contest Idea + make the world more sustainable Answered

It's terrible 'round here. So much water is just a flowing out of the lake and down the river. I think a contest would be just dandy.

I don't know the exact law, but here in New Mexico we are reqired to have a rainwater collection system for the roof of the new house we are building. Lawn s u c k s ! ! ! ! ! ! ! ! ! ! ! ! ! ! We need more environmental contests.

• Encourage watering of lawns with grey-water, via under-lawn pipes to cut down evaporation.
• Replace the grass - many lawns are ornamental, and do not need to survive traffic. Are there other, drought-resistant plants that grow to form a mat of green a few inches tall?
• Get local authorities or utility providers to give tax breaks to households that install rain-barrels and use nothing else to water the garden, or who re-direct the barrel-water to toilets and washing machines.
• I get the impression (from TV) that most American lawns are very exposed - a hedge or fence around the edge of a garden will shelter a lawn from wind, slowing evaporation and reducing the need for watering.
